This short note provides information on first known breeding events of Red-backed Shrike (Lanius collurio) both in the Castellon province and the Valencian Country. Al! the nests have been found in what has been defined as a typical breeding habitat for this species, so the species' presence in the province is expected to become usual or even more abundant in subsequent years. Shrikes may colonise new suitable areas, such as those found in els Ports, l'Alt Maestrat, l'Alcalatén and Tinença de Benifassà. [-]
